Patent GB-1039283-A (GB)
Title: Production of chemical compounds and of epitaxial films formed therefrom
IPC: C01B19/00
Filed: 1963-07-12
Abstract: A crystalline compound of an element from Group IIB of the Periodic System of Mendeleef with an element from Group VIB (an AIIBVI compound) is produced by contacting a IIB element with a hydrogen halide at a temperature at which reaction occurs and admixing the resulting gaseous product with a volatilized Group Vb element or compound in the absence of any oxidizing gas, gaseous hydrogen being present when the volatile Group Vb compound is a halide.  The Vb element may be sulphur, selenium or tellurium, the IIB element beryllium, zinc, cadmium or mercury and the reaction temperature may be 300-1200 DEG  C.  The product may be deposited as an epitaxial film on a compatible substrate of a cubic crystalline material which is an AIIBVI binary, ternary or quaternary compound, an AIIIBV compound, an AIBVII compound or on to silicon of germanium, which crystalline material is preferably orientated with its (100) crystallographic face (Millerian indices) exposed to the depositing compound (see Specification 1,039,283).  Mixed binary crystals or ternary and quaternary compounds AII(B1VI)1-x, (A1II)y(A11II) 1-yBVI and (AII1)y(A11II 1-y(B1VI)x(B11VI)1-x may also be prepared (0<x,y<1), e.g. CdSexTe (1-x), CdyHg(1-y)Te.  The epitaxial film and/or the substrate may be "doped" with Cu, Ag, Au, P, As, Sb to produce p-type or with B, Al, Ga, In, to produce n-type conductivity. Electronic devices containing a plurality of epitaxial layers of differing conductivity may thus be built up by successive deposition. Numerous examples are given.

Abstract: 1,102,537. Photographic photo-solubilizable silver halide emulsions. E.I. DU PONT DE NEMOURS & CO. June 30, 1965, No. 27784/65. Heading G2C. Photographic photo-solubilizable silver halide emulsions contain i) at least 90% of such an amount of an organic mercapto compound of such structure that a test given in the specification is satisfied, and ii) 0À015-0À075g per mole of silver of a cyanine, carbocyanine or merocyanine sensitizing dye. On coating the emulsion on a support, exposing imagewise and treating with a silver halide solvent, silver halide is selectively dissolved from the exposed areas leaving a positive silver halide image which may be reduced to silver. The presence of the dye increases general sensitivity and also optically sensitizes the emulsion. Organic mercapto compounds specified are 1-phenyl-5-mercapto-tetrazole and 2-mercaptothiazoles substituted in the 4-position by phenyl, p-bromophenyl, p-nitrophenyl, naphthyl, isobutyl, undecyl, octanoyl or cyclohexyl or in 5-position by phenyl. The silver halide solvent may contain K, Cs, Rb, Tl, Sr or Pb ions.

Title: Improvements in or relating to fowl products
IPC: A23L13/70
Filed: 1961-08-01
Abstract: In order to enhance the flavour of poultry meat, the live bird is injected with a seasoning material and a diffusion permitting agent exemplified by the enzyme hyaluronidase.  Seasoning materials are preparations of the oils of dill, sage, garlic, sesame, celery, allspice, anise, bay, caraway, cardamon, cassia, cinnamon, clove, coriander, cumin, fennel, ginger, mace, nutmeg, rosemary, tarragon, thyme, marjoram and oregano, of the oleoresins of capsicum, black pepper, ginger, sage and paprika, and liquid smokes (solutions of hardwood, e.g. hickory, distillates).  A single injection is made under the neck skin of the fowl.  The diffusion permitting agent allows entry of the seasoning material into the bird's vascular system, and sufficient time is allowed before despatch of the fowl for spread of the seasoning material throughout the flesh of the bird, times of 5 min.-2 hrs. being referred to.  An example is of injecting 8 week old chickens with 2 ml. of a dill oil preparation and 1 ml. of a physiological saline preparation of hyaluronidase having 150 turbidity reducing units/ml. (a measurement of the rate of turbidity reduction by the hyaluronidase of a hyaluronic acid-protein suspension), killing the birds after lapses of 30 min., 1 hr. and 2 hr., and storing the flesh under refrigeration for 6 days before cooking.

A connection path through a plurality of stages of co-ordinate multi-switches is selected by a common marker which is then immediately released, the establishment of the connection being dependent on the result of a subsequent testing process effected by a test device associated with part of the switching network formed by the stages of multi-switches. As shown, Fig. 1, the dialled digits are stored in an idle register RG seized by a pulse transmitter ZIG through a selector SW and are then transferred in a suitable form to a central marker MA by way of a distributer AK and a translator ZO. A signal is returned to the pulse transmitter ZIG which thereupon seizes its associated input to a two-stage co-ordinate switching network KA and causes the connection of the switch containing this input to the marker MA, which controls the selection of a suitable path through the network KA and is then released. The network KA comprises a plurality of two-stage co-ordinate switch arrays KF1, ... , KFy (Fig. 2) and the second stage AKV of each array is associated with a control circuit, Fig. 3 (not shown), which effects the final testing and establishment of a connection previously selected by the marker MA.
